Lady Gaga Channels Her Inner Marilyn Monroe

Lady Gaga rocks a pair of cat eye sunglasses while leaving her hotel on Monday (December 12) in New York City.

The 25-year-old pop star, with Marilyn Monroe‘s iconic blonde hairdo, signed autographs for a crowd of fans gathered around her car.

A charcoal sketch of a nude Gaga done by Tony Bennett is now up for auction on eBay.

Proceeds from the 18″ x 24″ portrait, which was signed “Benedetto” by the legendary singer, will benefit two charities – Gaga‘s Born This Way Foundation and Tony‘s Exploring the Arts.
